I wouldn’t do it. Nothing disappears 100%
There are several Internet archive sites where info is literally saved “forever.”
Even a Tryst page.
When you put in a telephone number it may return a result if it ever appeared anywhere.
I still get sales calls to my cell that was listed on startup website 9 years ago.
There are also paid sites that will do a deeper search.
Bonne chance.
Like I said it’s not my real phone number. I will cancel the line and move on
